I know this is a touchy subject, and I probably shouldn't go into it at all, but I want to.
I was born to a family of one absolutely faithful Lutheran and one churchless. My mother had conviction, she taught me to be good Christian and she taught me that science and faith don't clash, they can both exist at the same time. She was a doctor. My dad, the biochemist, doesn't care one way or the other if a god exists or not. He belongs to a church in Switzerland, but he doesn't like the institution. Neither did my mother, though she had more faith than many Christians I know.
This year, in July, I resigned from the Lutheran church. I had noticed over the years that I wasn't a protestant, I couldn't belong to a protestant church and fake my faith towards it.
So I resigned.
But I have my faith. I believe in God. I am a Christian. I'm just a very liberal, anti-papal Catholic. And I do not belong to any church...yet. Faith and church do not in my opinion go together. One can have faith without church and one can be part of a church without having any faith.
And I believe that religion and everything that goes in religious faith, should be everyone's personal issue, not something to be pushed on others, everyone should be allowed to be left in peace when it comes to faith.
If my faith is correct, and there is a hell and heaven, I know I am going to hell, and I am going to live my life to the fullest, even though I believe in this. Why? Because it's my business. It's my faith.
Your faith is yours and you are allowed to believe in whatever else I might not believe in. I dont' care, and neither should you.
Faith can be absolutely anything. It doesn't have to involve a god of any kind. It can just be hope and belief in something.
